In the 1980s, six children playing in the nearby hills returned home to report they’d seen the Virgin Mary and she spoke to them; a claim met with much skepticism at first, until others continued coming forward with stories of their own apparitions. To date, more than 15 million people have made the pilgrimage to Medjugorje’s Apparition Hill in hopes of experiencing their own vision, which makes this otherwise unassuming spot one of the most popular places to visit in Bosnia.
